Tennis ball machines

Hi guys

Im new to this forum and did a quick search on tennisball machines, and came up with some good pro's and cons about them. I just wanted to know if many players use them on a regular basis and which functions would most people like to see on the machines.

I say this because i know there is a line down the middle where some people swear by them and some, swear at them!

we actually manufacture tennisball machines in australia and have been working on the latest technology with these machines , any suggestions or feedback will be apprectiated!

Welcome to the forum. I feel a tennis ball machine's biggest hurdle is simply imitating a real opponents shot selection. I've seen ones that can vary angle and speed.. depth and spin - yet none can put all four aspects together in random. I am saying that at the moment, there is no substitute for a tennis partner.

Which ones do you like the best for ease of use, portability, and varying shots? I am thinking of a Lobster, but which model would work for an intermediate player who wants to play more. Partners are tough to find at her level during the school year.
